TaxAssist Accountants announces Karbon as a recommended practice management solution for its larger practices.

TaxAssist Accountants announces Karbon as a recommended practice management solution for its larger practices. TaxAssist Accountants has confirmed a strategic partnership with Karbon, the global leader in AI-powered practice management designed to help accounting firms improve visibility, strengthen workflow management and support sustainable growth. As part of its ongoing commitment to providing franchisees with access to best-in-class technology, TaxAssist Accountants will recommend Karbon as a practice management solution for the larger and more growth-focused practices within its network. Karbon is a highly configurable platform that brings together workflow management, team collaboration, email triage, document management, reporting and analysis, client work tracking and time capture in a single environment. The solution is designed to provide firms with greater visibility across work in progress, clearer accountability and the operational structure required to scale effectively. To support the rollout, TaxAssist Group-owned practices will serve as an implementation and development test bed. As some of the largest firms within the network, these practices provide an ideal environment to establish best practice processes, develop implementation guidance and create practical support resources that will benefit franchisees adopting the platform. Jo Nockels, Head of Practice Development at TaxAssist Accountants, said: "Good practice management sits at the heart of outstanding client service and a well-run practice. As firms grow, the ability to manage workflows effectively, maintain visibility across teams and create consistent processes becomes increasingly important. "Karbon offers the functionality, flexibility and scalability that ambitious, growing practices require. By implementing the platform within our Group-owned practices, we can develop a deep understanding of how firms can maximise benefits and ensure franchisees have access to proven guidance, training and support." The announcement reflects TaxAssist Accountants' broader commitment to helping franchisees build efficient, high-performing practices that can deliver exceptional client service while supporting long-term growth. While no single practice management solution is right for every firm, Karbon has been identified as a strong fit for practices seeking enhanced workflow control, improved team collaboration and greater visibility across client work. TaxAssist Accountants will continue to work closely with Karbon to develop onboarding, training and implementation support, helping firms realise the full benefits of modern practice management and creating the foundations for continued growth and operational excellence.

Digits expands its accounting firm platform with Ignition, Reach Reporting, and Karbon partnerships.

Digits expands its accounting firm platform with Ignition, Reach Reporting, and Karbon partnerships. SAN FRANCISCO, June 16, 2026 (GLOBE NEWSWIRE) - Digits, the world's first AI-native accounting platform, today announced partnerships with Ignition, Reach Reporting, and Karbon, connecting Digits to the tools accounting firms use to sell and get paid for work, deliver reporting, and run their practices. For years, the work of closing the books has consumed the time firms need to run the business. Month-end close takes weeks. Reconciliation is manual. Reporting data is stale before it reaches the reporting layer. Practice management tools got dragged into tracking close work that legacy platforms left unfinished. And advisory services are hard to scope, sell, and deliver when the team is still fighting to finish last month's books. Digits changes that foundation. Digits is designed to create and maintain the financial record, not merely store it. It collects source data, books transactions, reconciles accounts, manages schedules, applies quality checks, surfaces exceptions, and produces reporting-ready information - continuously. When the ledger closes the books, every tool built around it can finally do what it was designed to do: help run the firm's business. "Modern CAS firms do not run their business in one tool," said Jeff Seibert, CEO and Founder of Digits. "They sell work, collect payments, build reports, manage teams, and advise clients across a stack of specialized systems. Digits is the first ledger built specifically for firms because it was designed to do what firms actually need a ledger to do: close the books." A connected stack for modern accounting firms Ignition connects AI-powered revenue workflows to the ledger. Ignition is the leading revenue and billing automation platform for accounting and tax professionals, helping firms handle proposals, engagement letters, invoicing, payments, and pricing in a single AI-powered platform. With Digits closing the books, Ignition can do what it does best: helping firms sell smarter, bill accurately, and grow their business. The integration connects how firms sell, bill, collect, and price work with how that revenue is captured and understood in Digits, and lays the foundation for scope creep detection, profitability insights, and pricing optimization driven by live financial data. "AI should not just make firms faster at the same work," said Greg Strickland, CEO of Ignition. "It should help them understand which work is profitable, where scope is changing, and how to price with more confidence. That starts by connecting revenue workflows to the ledger." Reach Reporting connects Digits data to client-ready reporting and budgeting. Reach gives firms a polished, flexible reporting layer for dashboards, analysis, budgeting, and budget-to-actual workflows. With Reach connected to Digits, firms keep the reporting rhythms and client-facing experience they already rely on, powered by cleaner, more current financial data. The ledger maintains the record continuously; Reach turns it into insight. "Advisors are being marginalized," said Justin Hatch, CEO of Reach Reporting. "Clients are busier than ever. They need insights that are powerful, understandable, and immediately actionable. Reach + Digits gives advisors a way to elevate both client experience and firm margins." Karbon connects practice management to the accounting foundation. Karbon is the leading AI-powered practice management platform for accounting firms, helping teams manage workflows, centralize client communication, coordinate work, and maintain visibility across the practice. Digits and Karbon are partnering to bring practice management closer to the accounting foundation underneath, so firms can coordinate client work around books that are complete, accurate, and current. "The whole promise of AI is that it should handle repetitive tasks while accountants stay in control," said Ian Vacin, Co-Founder and Chief Partnerships Officer of Karbon. "Digits automates the reconciliation and categorization work. Karbon keeps teams focused on clients and strategy. Together, they let firms compress months of compliance work into days and redirect capacity into the advisory services that drive real growth." That is the role of a connected firm stack: each system keeps doing what it does best, while the ledger does the work it should have been doing all along. Ignition supports how firms sell and get paid. Reach turns financial data into reporting, dashboards, and budgets. Karbon helps teams orchestrate the work of the practice. Digits keeps the financial record complete, accurate, and current underneath them. Availability Digits and Ignition have partnered to connect revenue workflows with the ledger. The Ignition integration is available now for firms using both Ignition and Digits. Learn more Digits and Reach Reporting have partnered to bring Digits data into the reporting, dashboarding, analysis, and budgeting workflows firms already use. The Reach Reporting integration is available now for firms using Reach and Digits. Learn more Digits and Karbon have partnered to connect practice management with the accounting foundation underneath. More details are available in the Digits + Karbon announcement.

Karbon launches Kai, the AI coworker that knows your firm. By GlobeNewswire June 4, 2026 Karbon takes its most significant step yet toward becoming the AI operating system for accounting firms with numerous new AI capabilities SAN DIEGO, June 03, 2026 (GLOBE NEWSWIRE) - Karbon, the leading AI-powered accounting practice management software, today introduced Kai, an AI coworker built directly into the platform where a firm's client history, workflows, and communications already live.

Abacor + Karbon: the AI meeting assistant built for karbon-powered accounting firms.

Abacor + Karbon: the AI meeting assistant built for karbon-powered accounting firms. Co-founder, CEO May 14, 2026 If your firm runs on Karbon, your client work already lives in one place - timelines, work items, client groups, and communications, all tied together. The piece Karbon doesn't solve on its own is the meeting itself: the prep, the notes, the follow-up email, the action items that need to become work. That's where Abacor comes in. Abacor is the AI meeting assistant purpose-built for accounting firms, and the Karbon integration is one of the deepest in the product. Connect them once, and every client conversation flows back into Karbon - onto the right timeline, attached to the right client, with action items already extracted. Why accountants connect Abacor to Karbon. On average, an accountant spends 50 minutes preparing for and following up on every client meeting. Multiply that by every meeting on this week's calendar and you're looking at a full day, every week, lost to administrative work that doesn't bill. The Abacor + Karbon integration is designed to take that time back. Every meeting lands on the right Karbon timeline. Recordings, transcripts, and AI-generated notes push directly to Individuals, Organizations, Client Groups, or Work Item timelines - whichever fits the conversation. No copying, no formatting, no tagging. Your Karbon contacts sync into Abacor. When you import once, every future meeting can be linked to the correct client in seconds. New contacts added in Karbon flow into Abacor automatically on an hourly sync, so the two platforms never drift apart. Work Item timelines become living records. Pushing meeting notes directly to a Work Item means anyone picking up the engagement can see the full client conversation in context - not buried in someone's inbox or a separate notes app. Action items become trackable work. Abacor extracts every commitment, deadline, and follow-up from the conversation, so what gets said in the meeting actually gets done. What firms get back. The accountants using Abacor with Karbon describe the change in pretty consistent terms: they stop dreading the post-meeting wrap-up, they stop forgetting follow-ups, and they get hours of their week back. More importantly, the quality of the client record goes up. Every conversation is captured in full, summarized clearly, and attached to the right place in Karbon - which means the next teammate to touch that client can come up to speed in minutes instead of digging. For firm owners, that consistency is the bigger win. Client experience stops depending on which staff member happened to be in the meeting and how diligent they were about taking notes. Everyone delivers the same standard of follow-up because Abacor handles the busywork the same way every time. Get started. Connecting Abacor to Karbon takes under two minutes - generate the token in Karbon's integration settings, paste it into Abacor, and you're live. From the next meeting onward, your Karbon timelines will update themselves.
